Differential game anti-interception maneuver penetration/accurate strike guiding method with falling angle constraint

Abstract

A differential game anti-interception maneuver penetration / accurate strike guiding method with falling angle constraint comprises the following three steps: 1, building a three-body differential game model, wherein a dynamic model of three belligerent parties, a linear belligerent model of three belligerent parties, and a three-body differential game model are included; 2, performing reduction of dimensionality for the original three-body differential game model to obtain a new three-body differential game model; and 3, solving the new three-body differential game model based on the optimal control theory to obtain the optimal control law of a missile. Through adoption of the above steps, the differential game anti-interception maneuver penetration / accurate strike guiding method with falling angle constraint is achieved. According to the differential game anti-interception maneuver penetration / accurate strike guiding method, expressions are very simple, and physical significance of each term is clear; in addition, the differential game anti-interception maneuver penetration / accurate strike guiding method is large in penetration miss distance, high in falling point accuracy, and can simultaneously meet the falling angle constraint.

Description

technical field [0001] The invention provides a differential countermeasure anti-interception maneuver penetration / precise strike guidance method with a fall angle constraint, which relates to a differential countermeasure anti-interception maneuver penetration, fall point precision control and fall angle constraint control, and belongs to the field of aerospace technology and weapon technology Background technique [0002] With the development of modern guidance laws and anti-missile systems, the survival environment of missiles is deteriorating. Mobile penetration is an important means to improve the survival probability of missiles, so it is necessary to conduct in-depth research. [0003] Nowadays, there are two main types of maneuver penetration methods for missiles that have been studied more: procedural maneuver and optimal maneuver (the optimal maneuver is based on the assumption that the interceptor adopts the proportional guidance law (PN is directly used to represe...

AI Technical Summary

Problems solved by technology

Procedural maneuvering is highly practical and has little impact on the accuracy of the landing point, but the penetration probability is low; the optimal maneuvering maneuver has a high penetration probability, but it is easy to cause large deviations in the landing point
